2302EN V2.0.0 and KV-Nano Series Modbus RTU Connection Operating Manual

Remote I/O Module System Configuration List

The following table shows the specifications and descriptions of the remote I/O module system components:

Product Description

The remote I/O system consists of a main controller (GFMS-RM01S), digital input module (GFDI-RM01N), digital output module (GFDO-RM01N), power supply modules (GFPS-0202 and GFPS-0303), and an interface module (0170-0101). The interface module is used externally to convert KV-NC20L’s communication module (Modbus RTU) to a RJ45 connector. The main controller manages and dynamically configures I/O parameters. Users can choose the model or brand of power module and interface module they prefer.

KV-NC32T Connection Setup

This section explains how to connect the KV-NC32T using KV STUDIO software. For more details, refer to the KV Nano Series Communication Functions Manual.

KV-NC32T Hardware Connection
To connect the KV-NC32T, follow these steps:

1. The connector is at the bottom of the KV-NC20L communication module and uses RS485 connections.
2. Connect the COM (RS485 A/B) on the left of the FX5U to the interface module (1/2) to convert them to RJ45 connectors before connecting them to the main controller.

KV-NC32T Connection Setup

To set up the KV-NC32T connection:

1. Launch KV STUDIO and click on Unit Configuration on the left. Select KV-NC32.

2. Under Communication Settings, select KV-NC20L.

3. Use Port 2.

4. For Action Mode, select Modbus Master
   Interface: RS-485 (2-wire)
   Baud: Select 115200bps Stop
   Bit: 1 Parity
   Bit: None. Note that the communication format setting must be consistent with the connected device.

5. Program your communication.

Programming Example: Control with one GFDI-RM01N and one GFDO-RM01N

When DM0.0 receives a signal and is triggered, DM1000.0 outputs a signal as it is connected.
